In answer to your specific question about similar examples:
Uzzah - for touching the Ark when the cart was about to be upset. (2 Sam 6:6, 7)
Onan - for purposely refusing to make Tamar pregnant. (Gen 38:6-10) Admittedly, this account might be referring to Onan's repeatedly doing this. The text seems a bit ambiguous. I took your question to refer to a one time only/quick judgment. (In Onan's defense, I will say that he didn't get a chance to see the new video.)
Aaron's two sons who were executed by God for offering illegitimate fire (possibly also involving alchahol use on the job).
Another man who did something on the Sabbath. I can't remember what it was off hand (picking up sticks?), but it left Moses wondering what to do about it. The answer from Jehovah was to execute him. (Of course, the Sabbath law had already been given. Just no punishment prescribed.)
Adam & Eve - But they didn't die right away
These are some possibles that came to mind right away.
Edited to add: Sorry, I just reread your post and it said NT examples.
A possible NT example:
1 Cor 11:27-34 - Here, Paul says some of the Corinthians were judged for matters involving the Lord's Evening Meal. Verse 30 in particular mentions, "that is why many among you are weak and sickly, and quite a few are sleeping [in death]."
This is ambiguous at best. It doesn't actually say God made them "weak and sickly" or put them to death. Paul might have meant that because of their actions, God withdrew His Spirit and persons who might have benefitted from miraculous healing weren't. But it does link the 'weakness, sickness and death' as a result of their actions involving the Lord's Evening Meal.
